It certainly does make a difference performance wise. I did some
quick testing with netperf and netrate. Back to back boxes, using an
AMD x2 with bge nic and one intel box
CPU: AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ (2009.27-MHz 686-class CPU)
CPU: Intel(R) Core(TM)2 CPU 6400 @ 2.13GHz (2144.01-MHz
686-class CPU)
The intel is a DG965SS with integrated em nic, the AMD a Tyan with
integrated bge. Both running SMP kernels with pf built in, no inet6.
Intel box as sender. In this test its with the patch from yesterday.
The first set with the patch as is, the second test with -DEM_FAST_INTR.
